The BHP Billiton Group and Glencore Plc majority-owned Antamina mine in Peru is likely to double zinc output to between 340,000 tonnes and 360,000 tonnes in 2017, Reuters reported Oct. 10, citing the mine's General Manager Abraham Chahuan.
Annual copper output, meanwhile, is expected to increase to 430,000 tonnes in 2016 and 2017, slightly above the 2015 total of 412,000 tonnes.
"There's a lot of talk about how there are greater expectations for the price of zinc, and that's ... going to coincide with our much greater production of zinc next year," Chahuan said at a press conference.
The open-pit operation in Peru's central Andes is expected to tap a layer of zinc veins next year, which would allow the country to exploit potential price hikes as a shortage looms, the official added.
BHP and Glencore each hold a 33.75% stake in the mine, while Teck Resources Ltd. and Mitsubishi Corp. own interests of 22.50% and 10%, respectively.
